| 22 | General Remarks |
| 23 | --------------- |
| 24 | |
| 25 | Valid addresses are 0x18, 0x19, 0x1a, and 0x1b. |
| 26 | However, the device cannot be detected without writing to the i2c bus, so no |
| Jean Delvare | 0314b02 | 2009-10-04 22:53:41 +0200 | [diff] [blame] | 27 | detection is done. You should instantiate the device explicitly. |
